M51953A,B/M51954A,B
Voltage Detecting, System Resetting IC Series
REJ03D0776-0200
Rev.2.00
Aug 20, 2007
Description
M51953A,B/M51954A,B are semiconductor integrated circuits designed for detecting supply voltage and resetting all
types of logic circuits such as CPUs.
They include a built-in delay circuit to provide the desired retardation time simply by adding an external capacitor.
They fined extensive applications, including battery checking circuit, level detecting circuit and waveform shaping
circuit.
Features
Few external parts
Large delay time with a capacitor of small capacitance (td
100 ms, at 0.33
µF)
(M51953, M51954)
Low threshold operating voltage (Supply voltage to keep low-state at low supply voltage):
0.6 V (Typ) at R
L
= 22 kΩ
Wide supply voltage range: 2 V to 17 V
Wide application range
Application
Reset circuit of Pch, Nch, CMOS, microcomputer, CPU and MCU, Reset of logic circuit, Battery check circuit,
switching circuit back-up voltage, level detecting circuit, waveform shaping circuit, delay waveform generating
circuit, DC/DC converter, over voltage protection circuit
Recommended Operating Condition
Supply voltage range: 2 V to 17 V
